Specification of Letters Patent.

Patented June 25, 190'?a Application filed January 4, 1906. Serial No.294,599.

To all whom/ it may concern.'

Be it known that I, ROBERT WOERNER, a citizen of the Empire of Germany,residing at Mannheim, in the Empire of Germany, have invented a new anduseful Vegetable- Chipper, of which the following is a specification.

There are known vegetable cutters or slicers, in which the vegetables tobe cut are automatically fed in the manner, that the pressure upon thevegetables is produced by a lever mechanism which is actuated by hand.Such machines present, however, the defect, that the amount of pressureexerted upon the vegetables depends upon the operator, which isobjectionable for the ground, that he might unreasonablyso increase thepressure as to spoil the vegetables by mere crushing. Moreover in suchmachines the pressing plates, by means of which the pressure istransmitted to the vegetables, can not be raised sufficiently 'highabove the receivers or baskets to facilitate the introduction of thevegetables, and besides this the projecting levers of the mechanismrender the machine bulky and unwieldy. There is also the inconvenienceto be found in such ma-' chines, that it is not possible to produce thepressure in the proper direction at right angles to the vegetables forany position of the pressing plates, so that the whole mechanism is veryapt to jam.

My invention relates to improvements in such machines, whereby the saiddefects are avoided in the manner, that the required pressure upon thevegetables during the feeding ofthe latter is exclusively produced bythe weight of heavy pressing plates, which are positively guided in avertical direction, and moreover the advantage is obtained, that withthe greater machines a device is supplied, by means of which thepressing plates can be raised up to any height above the receivers forthe introduction of the vegetables, aclutch being provided forconnecting at will the said device with the driving gear and fordisconnecting the same. The chipping disk is either a cutting disk or arasping disk and both these disks may be exchanged at will, so that theso improved machine may serve either as avegetable cutter or asavegetable rasper. The machine is particularly suitable for cuttingcabbagcs.

I will now proceed to describe my invention with reference to theaccompanying drawings, in which` Figure 1 is an elevation of a largevegetable chipper with a cutting disk, partly in section, Fig. 1a, showsan enlarged viewof the upper end of the supporting rods; Fig. 1b, showsan enlarged view of the coupling clutch; Fig. 2 is a horizontal sectionthrough the same on the line A-B in F ig. 1, E ig. 3 is averticalsection on an enlarged scale through the line C-D in Fig. 2.

Similar letters of reference refer to similar parts throughout theseveral views.

' The machine shown at Figs. 1 to 3 consists of a frame, four receiversa, four pressing plates 7c, and the 'mechanism proper. The frameconsists of a ring e, three legs f f, a bow r, two standards 8 s, twocross pieces t t1 and a vertical rod n. The one leg f is provided with acaster f1, by means of which the whole machine can be transported, afterits two other legs f f have been raised a little. The ring c ispreferably provided with a groove along its periphery, in which balls uare permitted to roll. The circular cutting disk d is provided'on itslower side with a corresponding groove along its periphery, so that theballs u engaging in this groove not only support, but also guide thecutting disk d. A box g isdisposed beneath the cutting disk d forreceiving the chippings and is adapted to be drawn out in any knownmanner. For example the three legs f f. are shown as provided with`supports g1 g1, on which the boX g 'may be placed and from which it canbe taken off. The cutting disk d is shown as provided with four curvedknives'i 7L, which are fastened on it with screws h2 (see Fig. 3). Alongthe four knives 71 7L the cutting disk d is provided with four curvedopenings h1, through which the chippings can fall. The cutting disk d isconnected with the flange of a vertical shaft i, which latter is mountedto turn in a bearing on the bow 1^ and has fastened on it at the upperend a bevel wheel v. The two standards s s with the cross pieces t t1are fastened on the bow r by any suitable means. A horizontal shaft a:is mounted to turn in the two standards s 8 and has fastened on it alarge bevel wheel w and a fly wheel y1 with the hand crank 'y and aloose chain wheel z and a clutch g. The large bevel wheel w meshes withthe other bevel Wheel u and the IOO clutch g, which. may be of any knowncon- Y struction, is adapted for coupling at will the chain wheel z withthe wheel x2 fixed on shaft o; or for disconnecting it. (See Fig. 1b.)In the upper ends of the two standards s s a horizontal shaft o ismounted to turn, which has fastened on it a chain wheel z2 and twobelt-pulleys p1 p1. The two chain wheels z and z2 are connected by meansof an endless chain .21. Four cylindrical receivers or baskets a a openat top and bottom are secured above the cutting disk d by means of foursupporting bolts b Z1 and nuts on the ring e and by means of suitablestays a1 al of any known construction. Within these four receivers a afour weights or pressers Zc 7c of any known construction are guided,which are suspended from a four-armed crosshead m by means of fourvertical rods Z Z. The upper ends of the rods Z Z are slotted (see Fig.la) to render the four pressers Zc Zr independent of each other and topermit them to bear with their own weight on the vegetables to be cut orrasped. The crosshead m is guided on the vertical rod 11, alreadymentioned and is in turn suspended from the two belt-pulleys p1 p1 bymeans of two belts p p. The length of the four rods Z Z and of the twobelts p p is preferably so made as to prevent the pressers ZC Zr intheir lowest position from coming in contact with the four knives Z1,ZL, the cutting edges of which might otherwise get damaged.

A rasping disk may be provided for the machine and is arranged to rollon the balls u in the same manner as the cutting disk d. This disk isprovided with teeth and holes similar to those of known graters and canbe connected with the flange of the shaft i in place of the cutting disk(Z.

The machine is operated as follows: Zhen the vegetables are to be cut,the cutting disk d is put in and the chain wheel z is coupled with -theshaft by means of the clutch q. Then the shaft :r is rotated byturning'the hand crank y, so that the upper shaft 0 will equally be putinto rotation by means of the chain .el and the two pulleys p1 p1 willwind the two belts p p on them. Thereby the crosshead m with the fourrods Z Z and the four pressers ZC Zr will be raised until the latter aresufliciently high above the four receivers, when the hand crank y isstopped. After the vegetables (such as cabb ages or the like) have beenput in the four receivers a, c, the hand crank yis turned back to lowerthe crosshead .m with the four rods Z Z and the four pressers Ze Zr,until the latter bear on the vegetables. Thereupon the chain wheel z isdisconnected from the shaft a: by means of the clutch Q, so that thecrosshead m is permitted to sink by reason of its own weight and tounwind the two belts p p from their pulleys p1 p1, until the crosshead mis checked by its members resting on the lower ends of the slots in thefour rods Z Z. Now the hand crank y is turned to put the cutting disk Zinto rotation by means of the shaft the two bevel wheels w and c and theshaft i. The cutting edges of the four knives h will therefore cut orslice up the vegetables, which are constantly pressed downward by thefour pressers Zr Zr. The chippings will fall through the openings Ztl ofthe cutting disk d into the box g. It is evident, that the vegetableswill be cut up inthe proper manner, as the four pressers Zr Zc are atfull liberty to press on their respective charges and do not depend uponeach other. vWhen any or all the receivers a a have been emptied, thefour pressers Zr Zr are simultaneously raised in the manner describedand the four receivers a a may be recharged. When full, the box g isremoved, emptied and again replaced.

For rasping vegetables all that is required, is to replace the cuttingdisk d by the ras ping disk, the respective screws being removed andagain replaced. Afterward the machine is operated much the same asbefore.

The construction of the frame is immaterial and may be varied in anyknown manner.
